Cheapest hardware in Kolkata.

Have u search the Chandni area ?
Try contact Microdata they can give u better price (Ph: 22261299)

for zebronics card, u can try out Jai Mahavir, but i don't have the address.

Chandni

how is Tirupati Enterprises, do they offer low prices compare to chandni shops...

Well for Grfx card, and if the brand is XFX and also when u r looking at that model in Kolkata, i think would hard to find right now at chadni, but there is a place or shop in Old China Bazar Street, named Zindal Computers they stock XFX , may be they are distributer of that brand, but what i saw they do hold good stock of all XFX cards

There is no one place where you can find the cheapest of everything.You have to roam around and try several shops to get the cheapest deal.
